About Ceratocephala orthoceras DC.
Ceratocephala orthoceras DC. is a species of flowering plant that has the scientific synonyms Ceratocephala testiculata and Ranunculus testiculatus. It is native to Eurasia, and its common names are bur buttercup and curveseed butterwort. This plant is very small, typically only growing one to two inches tall, though it can reach up to four inches in height. It has small, dull yellow flowers, and hairy, somewhat dissected leaves. It produces a cluster of hard, spiny fruits called 'burs'. Like other members of the buttercup family, this plant is poisonous. Large populations of this species usually indicate that the land has experienced excessive disturbance. The species is classified as invasive in the northern and western United States. In sagebrush habitats, it is one of the first plants to bloom after snow melts.
